Wasm/WASI allows complex build logic to be written in full-featured languages like Rust and called from Nix, enabling things like parsing Go modules or creating derivations in non-Nix languages. Provenance adds signed metadata to store paths recording where and how they were built, with integration into FlakeHub Cache and GitHub Actions, with future TPM-attestation planned. Flake schemas let teams define custom flake output types beyond the fixed built-in list, making flakes more expressive and decentralized. The author frames these as the most transformative changes since Nix flakes were introduced, positioning Nix as a platform for the future of computing. ## Full article daily.dev links to this article rather than hosting it.
